Could NASCAR take a page from Formula 1 and IndyCar's playbook and institute hard- and soft-compound tires? Brad Keselowski thinks it could work while others, including Mark Martin and Jeff Burton, aren't so sure.</p>

Brad Keselowski isn’t afraid to question why something is or isn’t done in NASCAR. He’s inquisitive, reflective and thoughtful. Some ideas lead to fruitful discussions and some don’t.

Either way, Keselowski looks ahead, never satisfied with what is happening. It doesn’t mean he has the right answers for every issue or that every idea is wrong. What he does is make others ponder issues he raises.
